The study aimed to identify the effect of radius on step characteristics during bend sprinting. Eight sprinters undertook two ~80 m sprints in two different conditions through two capture areas (straight and bend) collecting whole-body kinematic data. Step Velocity on the straight was lower than Lane 2 on the bend for the left-to-right step, brought about by a greater Step frequency (SF). Right-to-left SF was significantly lower in Lane 4 in comparison to the straight due to a greater step time. Step time was greater in Lane 4 for the right step compared to Lane 2. A greater SF was observed for the left step compared to the right step in Lane 4 whilst a greater flight time was seen for the left step in Lane 2. Therefore, lane radius typical of indoor competition elicits performance changes during bend sprinting, warrenting further biomechanical analysis.
